To define the simulation region, add the EME solver object from the simulation dropdown
menu in the Main menu bar.
Note that there are three different solvers available in MODE Solutions.
You can add multiple solvers as long as they are all different types.
So it is possible that you have FDE, varFDTD and EME solvers in a single simulation file,
but you cannot have, for example, two EME solver regions at a time.
When there are multiple solvers in the object tree, only one of the solver objects can be
By default, the one most recently added becomes the active solver and will be used when you
run the simulation.
An active solver object is marked by its original orange color while inactive ones are greyed
If you want to re-activate your inactive EME solver, right-click on it and select "Set
When an EME solver is added in the object tree, cell and port groups are automatically
created under the EME object.
Cells and ports will be covered in the next section of ports, monitors and cells.
